Function Documentation

TAILQ_HEAD ( rte_driver_list  ,
rte_driver   
)
TAILQ_HEAD ( rte_device_list  ,
rte_device   
)

Double linked list of devices.

void rte_eal_device_insert ( struct rte_device dev)

Insert a device detected by a bus scanning.

Parameters
devA pointer to a rte_device structure describing the detected device.
void rte_eal_device_remove ( struct rte_device dev)

Remove a device (e.g. when being unplugged).

Parameters
devA pointer to a rte_device structure describing the device to be removed.
void rte_eal_driver_register ( struct rte_driver driver)

Register a device driver.

Parameters
driverA pointer to a rte_dev structure describing the driver to be registered.
void rte_eal_driver_unregister ( struct rte_driver driver)

Unregister a device driver.

Parameters
driverA pointer to a rte_dev structure describing the driver to be unregistered.
int rte_eal_dev_init ( void  )

Initalize all the registered drivers in this process

int rte_eal_vdev_init ( const char *  name,
const char *  args 
)

Initialize a driver specified by name.

Parameters
nameThe pointer to a driver name to be initialized.
argsThe pointer to arguments used by driver initialization.
Returns
0 on success, negative on error
int rte_eal_vdev_uninit ( const char *  name)

Uninitalize a driver specified by name.

Parameters
nameThe pointer to a driver name to be initialized.
Returns
0 on success, negative on error
int rte_eal_dev_attach ( const char *  name,
const char *  devargs 
)

Attach a device to a registered driver.

Parameters
nameThe device name, that refers to a pci device (or some private way of designating a vdev device). Based on this device name, eal will identify a driver capable of handling it and pass it to the driver probing function.
devargsDevice arguments to be passed to the driver.
Returns
0 on success, negative on error.
int rte_eal_dev_detach ( const char *  name)

Detach a device from its driver.

Parameters
nameSame description as for rte_eal_dev_attach(). Here, eal will call the driver detaching function.
Returns
0 on success, negative on error.
